Electroencephalogram? Check. Brain MRI? Check. That’s all you’ll need to have fun visualizing your brain activity with the open-source program OpenViBE (Open Platform for Virtual Brain Environments). Here’s some more info from the creators:
Open-ViBE is a general purpose platform for the development of 3D real-time virtual representation of brain physiological and anatomical data. Open-ViBE is a flexible and modular platform that integrates modules for brain physiological data acquisition, processing, and volumetric rendering.
When input data is the electroencephalogram, Open-ViBE uses the estimation of intra-cranial current density to represent brain activation as a regular grid of 3D graphical objects. The color and size of these objects co-vary with the amplitude and/or direction of the electrical current. This representation can be superimposed onto a volumetric rendering of the subject’s MRI data to form the anatomical background of the scene. The user can navigate in this virtual brain and visualize it as a whole or only some of its parts. This allows the user to experience the sense of presence (“being there”) in the scene and to observe the dynamics of brain current activity in its original spatio-temporal relations.
Perhaps one day this technology could be used to iron out the kinks in one’s brain-computer interface. If you happen to download this program and get it to work, send us your results and we’ll post about it!
